Degreasing drivetrain

I use filter coffee papers to filter the crap out of my degreaser so that I can re-use it. I re-lube with an oil bath and allow to drip free, and I filter that too. I bought a large container of finish line wet lube 12 years ago and split it with a friend. We had 1.7 litres each and we're still using it.

A good tip for cleaning cassettes without taking them off: I use a folded rag, and use the folded egde to 'floss' between the cogs, this cleans both faces of all cogs. Cassette comes up nice and shiny and it's pretty quick and easy. Do it with the bike on the ground and you can use the resistance of the freehub on the down stroke, and move it round on the up storke. I've not found special brushes very useful.

I do this after a spray of degreaser on chain and then wash off, or it can be done when the cassette is only a bit dirty, along with a wipe of the chain.
